The dry wedding is the standard sort of wedding in Christian culture. Sparkling cider is all you get. Dry weddings are mind-boggling to Anglicans, Catholics, mainline denominations and Europeans, but to the evangelicals that's just how it is.
Alcohol often isn't permitted on church grounds, especially in the Bible belt, so if your reception is in the fellowship hall then it's out of the question. But even off-site receptions for those in Christian culture serve no alcohol. The devout avoid being photographed while holding tea or cider lest it be mistaken for an adult beverage.
Many who now consider themselves Reformed were raised evangelical and for them drinking is newly permissible. At these weddings there is sure to be a showdown. The evangelical parents of the bride and groom might say they may have wine at the reception if they pay for it themselves, but this holds an unspoken message that there will be a relational price to pay if they defame their Christian reputation by serving wine.
